Reliability is a meaningful factor in business. Experienced buyers no matter of sector they get goods from, are really wise and keep in mind that trust is an important attribute. Therefore, they cannot be easily lured by various visions shown in TV or Web ads. They prefer to choose an entrepreneur, who they have always worked with. It is related to the fact that they are aware that not realizing the contract requirements would mean that the partner would lose his image of being trustworthy.
